T all whom it may concern:

Be it known that I, EDWARD 8-. Born), a citizen of the United States, residing at Philadelphia in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Frames, of which the following is a specification.

The object of the invention is to provide an improved metallic frame so constructed that it possesses great stren h and can be manufactured at comparatively small cost.

The features of my invention are of particular utility in frames for cushions such as are used in railway car-seats, but I wish it understood thaii they are in no way limited in this respect. I

My improved frame is preferably of rectan ar shape. and consists of a plurality of rams-sections secured together at their ends; each section is formed of sheet-metal pressedto the desired form and having open space between the sides thereof and flanges at the edges to facilitate securing them together. These flanges are arranged to provide a flange on the section extendin inwardly of the frame to which the ends of cross-slats for strengthening the frame as a whole may be secured. When the frame is used in the construction of a cushion, this flange is peculiarly formed to assist in giving the desired shape to the surface of the cushion. At the corners of the frame, the

frame-sections are secured together by means of separators extending into the abuttingends of the sections and having a plurality of openings into which the material of the sec tions may be driven to secure them-thereto Also, the frame-sections are cut away some- 4- what at the corners and curved cornerpieces are secured to adjacent sections 1 round the corners of the frame.

My invention will be better understood by reference to the accompanying drawings,

which show an embodiment thereof and in which Figure 1 is a top view of the frame broken away in part Fig. 2 is a section on -line 22 of Fig. 1, Fig. 3 is an enlarged Q0 view of one of the'orners broken away in part, Fig. 4 is a section on line 4-4 oi Fig. 3; Fig. 5 is atop view of the separator, Fig. 'G'isa sectipn on line 66 of Fig. 5, Fig. 7 is a view similar to Fig. 3 showing a modified form of corner construction, Fig. 8 is a section on line 8--& 7., and Fig. 9 is a view of a further modification of the corner construction.

Referring first to Fig. l of the drawings, the frame is of rectangular form and consists of two. side and two end frame-sections, 1 and 2 respectively secured together at their ends. Each trains-section formed of one or more members of sheet-metal pressed to the proper shape to provide open space be tween opposite sides thereof.

in Figs. 1 to l, each frame-section is shown as formed of a single piece of sheet metal one or which is provided with a flange and the other a fold 4: inclosing the flange whereby the edges of the section are secured together. The flange and fold at are so ruled as to constitute a flange extending inunrdly of the frame when the several sections are secured together, and if the frame to he used for a cushion, the inwardly extending flanges on the side members l are incl ned with reference to the plane of the frame so'that the inner edges are lower than the outer edges. The flange on each of the end-members is curved longitudinally thereof on an arc of large radius as shown at 5, Fig. 2,

the extreme ends thereof being on substantially the same level and inclination as the flanges on the sidemembers 1. The upper surfaces of the endmehibers 2 are pZO'fCILZbly curved longitudinally in substantially the same manner as the flanges thereon as shown in Fig. 2. A brace 6 extends across between opposite side members 1 and is secured at its ends to the flanges thereon; this brace is channeled, as shown, to give it greater strength.

In securing .the frame-sections together the ends thereof are brought together over a separator which extends into the abutting ends of the two sections'to assist in preventing collapse thereof; this separator is provided with a plurality of openings and the material of each section is driven into the openings in the separator onone side of the center line thereof.v I p In Figs.l to 6, is shown a form of separator consisting of a web 7 uniting a plurality of tubular men-risers 8. As the frame illustrated is of greater depth at one portion thereof than another, some of these tubular members 8 are longer than others.

In assembling the frame, two sections thereof are brought together with their beveled ends alining and half of the separator lying Within each of the sections, as

4 shown, and the material of the sections is sections and unites them by a strong neat joint in the manner above described. If deired, rivets 1'2 may be oserted in the openings in the separator, the ends of which may be countersunk, tohold the metal of the frame-sections in the openings more tightly.

' [In Fig; 9 a further modification of the form of the separator is shown having parts extending 'Well into the ends of theframe sections and provided with a plurality of openings into which the material oft-he sections is driven.

v In order toprovide rounded corners for the frame, the extreme ends of theseveral frame-sections are cut away, asi'ndicated at 13, and corner-pieces 14 are inserted and se-' cured in position at the corners. Each of these corner-pieces is'a piece of sheet-metal bent. to a right angle on a curve with a radius depending on the amount of metal cutaway" at the ends of the fraIne -sections and flanged inwardly at its upper and lower edges as shown at 15. In assembling the parts of the frame, the corner-piece 14; is inserted inthe ends of abutting sections and secured, as by brazing or riveting, in position with the curved bend therein filling the opening be tween the outer edges of the frame-sections and the ends thereof.

, The frame shown in Figs. 1 and 2 is particularly well adapted for use in the con-' struction of a seat-cushion for ear-seat. Thus, a plurality of wooden slats may be secured upon the inwaldly-extending flanges on the flttll'le-ll'lGlTlbGfS. These may extend lengthwise of thefraine and be seecured at their ends to the flanges on the sections 2,

- in which case the surfaces thereof will be arranget l on a curve substantially the same as that-of the flanges on the end sections. The

increased l'lllClUltHS of the frame-sections at thelouter edge. provides a smooth rounded edge for the seat, the uppcrsurfacc of which .is flush with that of the slats.

if desired, the slats may be curved longitudinally, and secured at their endsto the side members 1. Instead of'woodengslats, sheet-metal ones may employed, inzwhicli ease the outer "cdges of the frainemections would extend mp only a very short. distance above the flanges.

season Having now described my invention, What I claim as new therein and desire to secure 7 faces of the end members and the flanges thereon being curved in the direction of their len 'th, the flangeson the side members being inc ined downwardly of the frame and each of said flanges being below the upper surface of the member on wh ch it is formed so that the surface material of the cushion sup. ported on said flanges shall be substantially flush with the upper surfaces of the members, substantially as described. l
